WORKS, INC., OF FULTON, NEW YORK SELF-DUMPING RAG CATCHER FOR HEATINGENGINES Application filed March 29,

This invention relates to self-dumping rag catchers for beating engineswhich are running on old paper stock. It is not unusual for this sort ofstock to contain a high percentage of rags and strings, and it isnecessary at frequent intervals to thin up the consistency of the stock,and then lower a rack having open end tines into the channel of thebeater allowing the water and thin stock to pass between the tines whilecollecting the rags and strings upon them. It is customary to raise thisrack by cable or winch or by means of a motor driven gear train, andthen scrape the rags off on a platform where they are washed off with ahose and the good fibre washes back into the beater. The rags are cartedaway either to a dump or deposit or to a recovery plant.

The object of this invention is to provide a rag catcher apparatus toaccomplish the above stated results and having parts of specialconstruction and arrangement, with the additional function ofself-dumping.

The operator may simply stand at the side of the beater and actuate alever or throw a switch, setting in motion mechanism which raises therack or catcher and rags to a point some distance above the beater tub,at

which point the entire catcher assembly swings into a substantiallyinverted position allowing the rags to drop off.

The construction and arrangement of the parts of this invention areillustrated in the accompanying drawings.

Of the drawings Fig. 1 represents a side view of all the partsassembled, and Fig. 2 is a vertical section of the tub with a front Viewof this invention applied thereto.

Throughout the drawings and description the same number is used to referto the same part.

Considering the drawings, a tub 1 has thereon a screen platform 2, andrising from the tub are tracks 3 and 4 consisting of channel ironshaving near the top a bend 5 whereby the track extends above the tub intwo different directions with respect to the tub. The upper ends of thetrack members are secured to the floor 6 of the building, to which arealso 1933. Serial No. 139,983.

attached short beams 7 for the supportof the pulley mechanismhereinbelow explained.

Rollers 8 engage the tracks and carry the catcher 9 which comprises thespaced bars provided with inclined ends of customary formation. A cord10 from the catcher is led to a drum 11 on the horizontal shaft 12supported in bearin s secured to the beams 7. On shaft 12 is a loosepulley 13 driven by a friction wheel or roller 14 on a parallel shaft 15driven by a pulley 16 on the shaft deriving power from the belt 17leading to any source of motor force not shown. To connect the pulley 13and shaft 12, a friction clutch 18 is introduced arranged to be operatedby the rod 19 upon moving lever 20.

It will be understood that this invention is in no sense limited to thedriving mechaism illustrated, as this may be clearly modified orreplaced by other well known devices.

In operation the catcher is raised by the cord and as the rollers travelthe track the catcher reaches the position shown in broken lines and issubstantially inverted, dumping any rags, strings and the like upon theplatform 2. By suitably working the lever 20, a shaking movement may begiven the raised catcher to loosen its load.

Having now described this invention, I claim 1. In a rag catcher, incombination with a tub, a screen mounted on the tub, a track extendingabove the tub in two different directions with respect to the tub, a ragcatcher constructed to travel the track, and means for raising thecatcher and for controlling its movements whereby the catcher may beinverted and dumped above the screen.

2'. In a rag catcher, in combination with a tub, a track extending abovethe tub in different directions with respect to the tub, a rag catcherconstructed to travel the track, and means for raising the said catcherand for controlling the movements thereof whereby the catcher may bedumped above the tub.

3. In a catcher, in combination with a tub, a track extending above thetub in different directions angularly with respect to the tub, a screensupported by the tub, a catcher provided with spaced bars havinginclined end portions and constructed to travel the track, and means forraising the said catcher and for controlling the movements thereofwhereby the catcher may be inverted 5 and dumped above the said screen.

4 In a rag catcher, in combination with a tub, a track extending abovethe tub in two different directions angularly with respect to the tub acatcher provided with spaced 10 bars having inclined end portions andconstructed to travel the track, and means for raising said catcher andfor controlling the movements thereof whereby said catcher may beinverted and dumped above the tub.

1 In testimony whereof I afliX my signature.

GEORGE D. STEVENS.
